WELCOME
TO THE BERGLES BARREL SYSTEM. WITH PROPER CARE AND USE THIS WILL LAST A
LONG TIME. THIS DOCUMENT IS FOR ENTERTAINMENT ONLY. IF YOU CHOOSE TO BUILD THE
AIR CANNON, IT IS YOUR SOLE RESPONSIBILITY FOR ANY ACTION DONE WITH IT AND ANY
DAMAGE CAUSED. DO NOT SHOOT THIS CANNON DIRECTLY AT ANOTHER PERSON. IT IS MADE
TO LOB PAINT OVER OBJECTS AND LONG DISTANCES. THE PAINT SHOULD RAIN DOWN INSTEAD
OF DIRECT FRONTAL SHOTS. ALL FITTINGS AND PIPE USED MUST BE SCHEDULE 40 PVC. THE
FITTINGS SHOULD BE PRESSURE FITTINGS NOT STANDARD PLUMBING FITTINGS. PRESSURE
FITTINGS HAVE A DEEPER HUB AND BETTER SIDEWALL STRENGTH. MAKE SURE TO USE A GOOD
QUALITY GLUE AND CLEANER. SPEND THE EXTRA AND GET THE GLUE AND CLEANER BY THE
QUART. WHEN GLUING FITTINGS MAKE SURE TO CLEAN THEM PROPERLY AND TO LET DRY
BEFORE ADDING GLUE. ONCE GLUED HOLD IN PLACE FOR 10 TO 20 SECONDS SO FITTING DO
NOT BACK OUT OR MOVE. ONCE YOU HAVE THIS BUILT IT CAN BE MOUNTED BY THE YOKES
THAT STICK OUT EACH SIDE. A TRADITION CANNON MOUNT COULD BE USED. WHEN YOU
CHOOSE A SIZE FOR YOUR INNER BARREL MULTIPLY IT BY 2 TO GET THE OUTER SIZE
BARREL NEEDED. MY FIRST WAS A 1.5 INCH INNER BARREL SO I USED a 3-INCH OUTER
BARREL. ITS UP TO YOU HOW BIG YOU WANT TO GO? BUT THE BIGGER THE BARREL THE MORE
AIR IT WILL SUCK.
GOOD LUCK!!!!
PARTS REQUIRED
1)
15 FEET SCHEDULE 40 -
3 INCH PVC PIPE
2)
15 FEET SCHEDULE 40 -
1.5 INCH PIPE
3)
3 REDUCER BUSHINGS
3 INCH TO 1.5 INCH (NOT THE
CONES)
4)
1 SCHEDULE 40 PRESSURE T - 3 INCH

10)
1 THREADED COUPLING BY HUB SCHEDULE 40- 1.5 INCH THIS
MEANS ONE SIDE HAS THREADS AND THE OTHER IS A HUB THAT GETS GLUE. YOU CAN USE
INSIDE THREADS OR OUTSIDE THREADS. IT IS UP TO YOU. THIS WILL OPEN FOR YOUR
BREACH TO LOAD THE PAINT INTO PLACE
11)
1 THREADED PLUG OR CAP TO FIT WHAT YOU USED IN ITEM #10
12)
1 QUART OF GOOD PVC GLUE (CLEAR) AND ONE QUART OF CLEANER
BEFORE STARTING
BEFORE YOU START LAY ALL THE
PIECES OUT ON THE FLOOR IN THEIR GENERAL SPOT WHERE THEY WILL GO. MAKE SURE THEY
ARE ALL THEIR. YOU DO NOT WANT TO BE RUNNING TO GET MORE RIGHT IN THE MIDDLE OF
THINGS. AND DON’T USE ANY OLD SEWER PIPE!!! I DO NOT WANT ANY TURD BALLS
FLYING AT ME.
ANY PIECE PIPE OR FITTING SHOULD BE CLEANER AND LET TO DRY
BEFORE YOU PUT GLUE ON IT. WHEN YOU GLUE IT USE A LOT OF GLUE AND WIPE OFF THE
EXCESS AFTER THE PIECE IS IN PLACE. YOU DO NOT WANT ANY VOIDS IN THE JOINTS. ONE
WAY TO SOLVE THAT IS TO TURN THE FITTING A ¼ TURN TO SMEAR THE GLUE INSIDE THE
JOINT AND HOLD IT IN PLACE UNTIL IT SETS UP. MAKE SURE THE FITTING LINES UP
BEFORE IT IS DRY.
CANNON SIZE
I HOPE BY NOW YOU KNOW WHAT SIZE YOU WANT AND HAVE
PURCHASED THE FITTINGS ACCORDINGLY. JUST MAKE SURE TO DOUBLE THE OUTER SIZE
COMPARED TO THE INNER BARREL. THESE DIRECTIONS ARE FOR A 1.5 INCH INNER BARREL
WITH A 3 INCH OUTER BARREL. I KNOW ONCE YOU GET UP INTO THE 6-INCH SCHEDULE 40
RANGE THESE FITTINGS START TO GET VERY COSTLY. BUT IF YOU GOT THE MONEY YOU CAN
MAKE IT HAPPEN. AND THAT IS MY NEXT CANNON a 6X3 BARREL SYSTEM.
STARTING OUT
DETERMINE
WHAT YOUR TOTAL BARREL LENGTH WILL BE FIRST. MY FIRST BARREL THE FRONT SECTION
IS 6 FEET LONG. THAT IS IN FRONT OF THE CROSS. BEHIND IT I HAVE 3 FEET WITH THE
VALVE ON THE END. THAT ADDS UP TO A 9 FOOT BARREL. VERY HEAVY FOR A 6 WHEELER OR
QUAD OR GOLF CART TO HAVE IT MOUNTED THERE. BUY PIPE WITH THE BELL END ON. THIS
MAKES FOR A NEAT MUZZLE AT THE END. THE YOKES THAT STICK OUT THE SIDE WILL BE
USED FOR MOUNTING THE GUN ONCE IT IS DONE. YOU COULD MAKE THEM
LONGER THAN WHAT I STATED BUT IT WILL JUST TAKE MORE AIR TO FILL. THE
PICTURE BELOW IS FROM THE TOP. MOST OF THE REST WILL BE A SIDE VIEW AND THE
CROSS-WILL JUST IS A CIRCLE ON THEM. SO LETS GET GOING AND GET THESE PIECES
READY. CUT YOUR MAIN BARREL WITH THE BELL ON. IF YOU DON’T HAVE A BELL OR HAVE
TO CUT IT OFF JUST INSTALL A COUPLING TO SIZE AND RE-GLUE. CUT TWO YOKE STUBS
ABOUT 16 INCHES LONG. CLEAN ALL SURFACES THAT WILL BE GLUED IN THIS STEP. THEN
GLUE IN THE MAIN BARREL AND THE STUBS AND GLUE A CAP ON ONE YOKE. YOU MIGHT HAVE
TO REACH INSIDE BEFORE IT IS ALL DONE SO LEAVE ONE CAP OFF FOR NOW. I HAVE NOT
DECIDED IF THE CENTER OF THE BARREL SHOULD HAVE SOME TYPE OF FOAM UNDER IT TO
KEEP IT FROM WOBBLING ON THE INSIDE. ONCE IT IS GLUED IT WON’T COME OUT. BUT
IF YOU DON’T LIKE THE INNER BARREL MOVEMENT USE SOME INSULATING FOAM OR
SOMETHING TO GO UNDER THE BARREL. DO NOT BLOCK OFF THE FRONT AIR CHAMBER WITH
WHAT EVER YOU PUT IN THERE.
ONCE YOU HAVE THEM GLUED IN PLACE IT SHOULD LOOK LIKE THE PICTURE BELOW. IF NOT GIVE UP NOW; YOU HAVE NO PLUMBING SKILLS AT ALL
NEXT STEP
THIS STEP WILL DETERMINE HOW FAR BACK THE VALVE SITS. I HAVE ABOUT 3 FEET BEHIND THE CROSS AND IT IS FRONT HEAVY. LAY THE T DOWN NEXT TO A PIECE OF THE MAIN PIPE AND MEASURE 3 FEET WITH THE T AND MAKE YOUR CUT THERE. REMEMBER THE PIPE WILL GO INTO THE T ABOUT 3 INCHES AND INTO THE CROSS-ABOUT 3 INCHES SO MEASURE FOR THAT DIMENSION. CLEAN ALL JOINTS TO BE GLUED AND ASSEMBLE WHEN DRY. IT SHOULD LOOK LIKE THE SECOND PICTURE BELOW. MAKE SURE THE T IS FLAT TO THE TOP OF THE PIPE. IF YOU CAN PUT AN EVEN SIZE SPACER UNDER EACH YOKE TO LEVEL BARREL FROM LEFT TO RIGHT. YOU CAN THEN LAY A LEVEL ACROSS THE TOP OF THE T WHEN GLUING TO MAKE SURE IT IS PARALLEL TO THE YOKES
NOW GET THE 3 REDUCER BUSHINGS AND A TOOL THAT WILL TRIM OUT THE PIPE STOP ON THE SMALLER DIAMETER. YOU WILL TRIM OUT THE ENTIRE STOP SO THE INNER BARREL WILL SLIDE INTO THESE SNUG BUT NOT LOOSE. IF YOU HAVE THEM TO TIGHT IT COULD LOCK UP DURING GLUING AND WRECK THE PROJECT. THE GLUE WILL HELP THEM SLIDE WHEN THAT TIME COMES. BUT ONLY FOR A LITTLE BIT. MAKE SURE TO USE LOTS OF GLUE WHEN THAT STEP HAPPENS.
ONCE YOU HAVE THEM TRIMMED TO SIZE .THE INNER PIPE SHOULD SLIDE THROUGH. GO AHEAD AND GLUE ONE BUSHING INTO THE MUZZEL END AND ONE INTO THE TOP OF THE BIG T. MAKE SURE NO GLUE GETS ON THE INSIDE AREA OF THE BUSHING. IF GLUE DOES GET INSIDE AND YOU DO NOT SEE IT. YOU WILL HAVE PROBLEMS WHEN YOU GO TO SLIDE THE PIPE THROUGH IT LATER. JUST TAKE A ROUND FILE AND REMOVE IT.
YOU SHOULD NOW BE THIS FAR ALONG.
NOW TAKE YOUR INNER BARREL PIPE AND SLIDE IT IN FROM THE
BACK ALL THE WAY UP TO THE FRONT BUSHING. THE FRONT BUSHING SHOULD BE DRY BY
NOW. YOU ARE GOING TO BE PUSHING AGAINST IT SO BE SURE IT IS. MAKE SURE ALL
SURFACES TO BE GLUED ARE CLEANED AND LET TO DRY BEFORE GLUING.
DOES THE INNER PIPE STICK OUT THE BACK END BY AT LEAST 1
FOOT OR MORE?
IF IT DOES NOT YOU WILL NEED TO GET A LONGER PIECE. MAKE
SURE YOU HAVE ENOUGH FOR THE VALVE ASSEMBLY. WE WILL BE TRIMMING SOME OFF FAIRLY
SOON.
THE PIPE THAT IS STICKING OUT THE REAR END WILL GET CUT OFF DEPENDING ON WHAT VALVE YOU USE. WE WILL NEED TO DRY FIT THE VALVE PIECES TO GET A GOOD IDEA WHERE THE SMALL PRESSURE T WILL GET MOUNTED ON THE BACK. ONCE WE KNOW THAT DIMENSION WE CAN CUT THE EXCESS OFF THE INNER BARREL AND GLUE IN THE BACK REDUCER BUSHING AND THEN THE T. DO NOT PUT THE T ON WITHOUT THE BACK REDUCER BUSHING GLUED IN FIRST. WHEN GLUING THE BACK BUSHING IN YOU WILL HAVE GLUE ON THE INSIDE AND THE OUTSIDE OF THE BUSHING. TO HELP IT SLIDE WIPE GLUE OVER THE WHOLE END OF THE INNER PIPE WHERE THE BUSHING HAS TO SLIDE. PUT GLUE INSIDE THE HUB ON THE BIG T ALSO. HOLD IT IN PLACE WHILE WIPING ALL THE EXTRA GLUE OFF THE SMALL BARREL.
Valve Time
LOOK AT THE PICTURE BELOW. ASSEMBLE THE VALVE COMING OUT OF THE FIRST 90-DEGREE ELBOW. GLUE IT UP TO THIS POINT
NOW YOU NEED THE LAST SMALL T AND THE LAST 90 DEG ELBOW.
AS YOU CAN SEE THE 2 PIPE STUBS THAT OUR POINTING OFF THE BACK OF THE GUN IS
WHERE THESE GO.
MEASURE THE LENGTH OF THE SPACE BETWEEN THESE AND CUT A
STUB TO GO BETWEEN YOUR LAST 2 FITTINGS. THE 2 PIPES COMING OFF THE GUN WILL BE
SLIGHTLY STAGGERED IN LENGTH DO TO THE FACT THE SMALL T IS LONGER THAN THE 90
ELBOW. CUT THESE PIPES SO THE LAST 3 PIECE SECTION WILL HANG SQUARE TO THE
BACK OF THE GUN. ONCE YOU OUR SURE YOU HAVE THE RIGHT LENGTH.
LOOSE FIT THE SMALL T AND THE ELBOW AND THE PIPE THAT GOES BETWEEN THEM
ONTO THE GUN. IF EVERYTHING LINES UP GLUE THE 3 PIECE SECTION TOGETHER FIRST AND
GLUE THAT 3PIECE SECTION AS A WHOLE ONTO THE LAST 2 PIPE STUBS COMING OFF THE
BACK OF THE GUN. IT SHOULD LOOK LIKE THE PICTURE THAT IS ON THE TOP OF THE NEXT
PAGE. MAKE SURE YOUR VALVE OPENS AND CLOSES BEFORE THE GLUE SETS UP. JUST INCASE
YOU GOT SOME IN
THERE, OPEN AND CLOSE IT A FEW TIMES JUST TO BE SURE.
LAST STEP GLUING THE BREACH
GET
YOUR LAST PIECE THAT SHOULD BE A THREADED HUB. CUT A SMALL STUB THAT IS JUST
LONG ENOUGH TO FIT BETWEEN THE COUPLING AND THE SMALL T AND GLUE IT INTO THE
SMALL T AND THEN GLUE THE COUPLING ONTO THAT STUB. MAKE SURE TO WIPE ANY GLUE
FROM THE INSIDE OF THE BARREL BEFORE
IT DRIES. IF YOU PLAN TO SHOOT STUFF OTHER THAN PAINTBALLS. LIKE VEGGIES AND
SNOW BALLS YOU MIGHT WANT TO GO TO AN OUTSIDE THREAD ON THE BACK. I FOUND WITH
THE INSIDE THREAD SNOW WOULD GET INTO THE THREADS AS I PUSHED THE BALL IN. SO
RIGHT NOW I AM LOOKING FOR A FITTING THAT GLUES ON WITH THREADS ON THE OUTSIDE
SO I CAN JUST SCREW THE CAP ON TO FIRE
ONCE THAT IS DRY AND THERE IS NO GLUE IN THE THREADS YOU
MAY LOOSE FIT THE THREADED PLUG IN THE INTO THE BACK.
THE FINAL STEPS HERE ARE TO DRILL AND TAP TWO HOLES INTO
THE TOP OF THE CROSS AND INSTALL A PRESSURE GAUGE AND A SAFETY RELIEF VALVE. I
CHOSE THE CROSS-BECAUSE I BELIEVE IT IS THE STRONGEST PIECE IN THIS. IF YOU WANT
TO MOUNT THEM REMOTE ON A PANEL AND JUST RUN YOUR AIRLINE TO THE CROSS GO RIGHT
AHEAD. JUST MAKE SURE TO HARD PLUMB THEM IN SO THEY CANNOT BE JUMPED OUT OR OVER
RIDDEN. THE PIPE HAS A GOOD PRESSURE RATING. I F YOU CHOOSE TO IGNORE THAT AND
FILL THE CANNON WITH NO SAFETY DEVICES YOU WILL GET HURT. WHEN PLASTIC EXPLODES
IT EXPLODES LIKE GLASS. AND YOU WILL GET HURT!!! THE PICTURE ON THE NEXT PAGE
SHOWS THE RELIEF VALVE AND GAUGE LOCATION.
AIRLINES
SOME
OF YOU WILL COME UP WITH BETTER IDEAS ON HOW TO REGULATE YOUR PRESSURE FOR
FIRING. ON MY HPA TANK I HAVE A MANUAL VALVE THAT I OPEN SLOWLY SO NOT TO SPIKE
THE BARREL. I THEN WATCH THE GAUGE FILL UP TO 20LBS. THIS IS WHERE YOU SHOULD
TAKE YOUR FIRST SHOT. THIS IS TO BE SURE YOU HAVE AMPLE DISTANCE DOWN RANGE. A
SHORT STORY ON VELOCITY. I DECIDED I WOULD SHOOT OUT A SNOWBALL TODAY. I HAD THE
GUN LYING ON THE GROUND, IT WAS ELEVATED AT A 10 TO 15 DEGREE ANGLE. I USED A
BICYCLE TIRE PUMP TO GET THE GUN UP TO JUST UNDER 30 PSI OF PRESSURE. BEHIND THE
SNOWBALL I ROLLED UP A SMALL PIECE OF SOFT FOAM TO SEAL THE BARREL. I PUSHED THE
LOAD IN PAST THE SMALL T. I REACHED BACK AND TURNED THE VALVE .IT WAS A SMALL
POP AND I FIGURED IT WOULD JUST GO BOUNCING DOWN THE DRIVEWAY. I
WAS I LUCKY NOBODY WAS WALKING DOWN THE SIDEWALK AT THAT TIME. I LOOKED
UP JUST IN TIME TO SEE THE SNOWBALL ON A DIRECT COURSE OF FLAT TRAJECTORY
HEADING FOR THE NEIGHBORS HOUSE. LUCKY FOR ME IT HIT A TREE BRANCH ABOUT 12 FEET
IN THE AIR ABOUT 60 YARDS AWAY AND JUST VAPORIZED.
UNDER YOUR RELIEF VALVE INSTALL A T
SO YOU CAN HOOK UP AN AIR NIPPLE FOR FILLING OR HARD PLUMBING YOUR SUPPLY
LINE IN. AS FOR WHAT TYPE OF LOADS TO USE THAT IS UP TO YOU. I HAVE GOOD LUCK
WITH THE SOFT FOAM BEHIND THE PELLETS FOR THE PUSH OUT. I AM NOW WORKING ON
LOADING THEM INTO TOILET PAPER ROLLS FOR PRELOADED SHELLS. I JUST TAKE A PLUNGER
AND PUSH THE LOAD OUT INTO THE BARREL
IN FRONT OF THE SMALL T BEFORE I FIRE. THEN I SET
THE CARDBOARD TUBE ASIDE AND CLOSE THE CAP ON THE BACK. AND LOOK DOWN RANGE FOR SAFETY AND PULL THE VALVE.
GOOD LUCK AND USE THIS WITH CARE!! STUPID IS AS STUPID
DOES SO THINK TWICE BEFORE YOU FIRE IT. AND KNOW
WHAT YOUR TARGET IS.
